The Anderson occurrence is located at an elevation of approximately 1000 metres on a south west facing slope, between Babine and Taltapin lakes and approximately 2.7 kilometres west- south west of Taltapin Mountain.

The geology of the region consists of: 1) a Mississippian to Triassic Cache Creek Group oceanic volcanic and sedimentary assemblage 2) the Upper Triassic dominantly mafic volcanic Takla Group 3) the Lower to Middle Jurassic Hazelton Group mafic to felsic volcanic and sedimentary rocks 4) the Upper Cretaceous to Lower Tertiary Ootsa Lake Group sedimentary and volcanic rocks and 5) the 0ligocene and Miocene Endako Group. The region has been intruded by the Lower Jurassic quartz monzonite to granodiorite Topley Intrusive Suite, Upper Jurassic plutons of the Francois Lake Suite and plugs and stocks related to Upper Cretaceous and Tertiary volcanism.

The area of the Anderson showing is underlain mainly by Francois Lake Intrusive Suite rocks. However, the showing is in a roof pendant of well banded greenstones of the Cache Creek Group. These rocks are carbonatized and silicified. Grey augite andesite dikes cut both the greenstones and granitic rocks. Galena and pyrite mineralization occur in quartz veins 5 centimetres to 25 centimetres wide striking approximately 120 degrees. The veins also contain a little chlorite and white mica. Only a few sparsely mineralized zones were exposed by considerable stripping and 15 metres of adit.
